Even the most routine maintenance you perform can have lasting environmental effects. Did you know that keeping your tires properly inflated can save gallons and gallons of gas every year -- as much as 3%! Changing your air filter can also make an impact on gas mileage. There are really no auto maintenance tasks that won't be beneficial to your car's efficiency, and that's going to help air quality.
Kill two birds with one stone and celebrate Earth Day by performing some summer maintenance. You'll be doing your part environmentally and keeping your car in shape at the same time. You should also check out the Earth Day Network Homepage for more earth conscious tips.
